Abstract：Based on the actual project case of a logistics park,solar energy resources and consumption conditions of the project are analyzed. The key points of design of the PV system are discussed from the aspects of the comparison and selection of grid‑connection schemes for the design of PV system,the selection of grid‑connected voltage level,PV array calculation and inverter model selection,the selection of PV power to inverter power ratio of inverter,and the capacity calculation of transformer at the grid‑connected step‑up substation.

Key words：distributed PV;grid‑connected voltage level;PV module;series voltage;inverter;MPPT;PV power to inverter power ratio;step‑up substation

摘　要：结合某物流园区工程实际案例，分析项目太阳能资源及消纳条件，从光伏发电系统设计中并网方案比选、并网电压等级选择、光伏阵列计算与逆变器选型、逆变器容配比选择、并网升压站变压器容量计算等方面，探讨光伏发电系统设计要点。
